Help me choose a new loadout

So my current thought is...

Set 1:

Midrange (AR)

Very Close range (pistol/shotgun - could go SMG)

In this set, having an AR with single fire for longer mid range, and switching to auto in close entanglements. With the vclose range for quick damage in those intimate moments.

Set 2:

Mideange (Marksman)

Close range (SMG)

Gone with SMGs here for the close range as there is that crossover gap where a very close range and a marksman won't do well at.

Set 3:

Long range (Sniper)

Midrange (AR)

Similar here. If you go sniper and close range you could get caught out at Midrange. 

I'm probably going to favour set 1 for now and see how I'll get on. 

I'll base my weapons selection based on what main weapon I fancy running, then pick up what's available. And potentially allow attachments influence selection .... if running set 1 but I have a purple energy mag I may pick it a volt as my close range. My AR will be Flat, 301, or Hem based on whats available and what attachs I have.

This also makes me a bit freer to switch between sets mid game with not too much thinking.
